Specification of Letters Patent.

Patented June 1, 1909.

Application led June 17, 1908, Serial No. 438,923.

To all whom it may concern: i

Be it known that I, RAFAEL G. PRENDES, l a citizen ot the Republic ofCuba, and a resi- F dent of Habana, Cuba, have invented a new f andImproved Printing-Machine, of which the lfollowing is a full, clear, andexact description'.

The object of my invention is to provide a printing machine which has anendless belt to which the characters are secured, means being providedto ink. said characters, and means being also provided to move the beltineither direction by a step-by-step movement, and also to move th(`belt rapidly so that a number of characters will pass the openinfJr inthe casing quickly in succession.

In this specification I will describe the preferred form of myinvention, but I do not limit myself thereto, as I consider myselfentitled to all forms and embodiments of the invention which may be heldto fall within the scope of the appended claims.

' In the drawings similar characters of ref' erence refer to similarparte in all the figures, in which-- Figure 1 is a side elevation of theinvention., part ol the outer casing being removed; Fig. 2 is asectional plan' view on thc line 2-2 of Fig. 1; Fig. 3 is an enlarged-view showingl my improved method of connecting and disconnectlng thetwo lines of gearing; Fig. 4 is a sectional View on the line 4-4 of Fig.3; Fig. 5 is an enlarged view showing the esoapement, and my method ofoperating it; Fig. 6 is an enlarged view showing the endless belt withcharacters attached projecting through the casing, so that thecharacters may be stamped on the writing mate-- rial; Fig. 7 is anenlarged plan view of one of the characters; Fig. 8 is a side elevationol the same, and Fig; 9 is an enlarged sectional view showing thesprocket wheel which is journaled at the base of the casing, which willpermit the characters to rotrude so that theyl may be stamped. on t 1cwriting ma-v teria As will be seen by referring to the drawings, thetypewriter is in the form of a pencil, and is adapted to be held verymuch the saine way as pencils and pens, but with the lingers on thethumb pieces l` and 2, and the thumb on the arm 3 which is adapted to oerate the crank l secured to a shank 5. ln the easing 6, which may bc olany approved .1,4 on the members 1.1

form, is Journaled a sprocket wheel 7 at the base of the casing, whichwill permit char-v acters on a belt 9 to project beyond the casing sothat they may be stamped on the writing material, and there is alsojournaled in said casing 6 near its top a much larger wheel 10 on whichthe belt E1 also travels. The' belt 9 may be constructed in the forni ofa sprocket chain with members 11 pivoted together, and on` which may besecured the characters 8. At the rear side of the said members 11 yareprojections 12 which are adapted to lit in the concave surfaces 13 inthe sprocket wheel 7. There are also flanges on which may be printedmarks which will identify the charactor which appears on the uppersurface of the member 11.

'lhe wheel 10 is secured to a shaft 15 which is journaled in the casing6, and to this shaft 15 are also secured gear wheels 16 and 17, whichmay be approximately of the same diameter. There is secured betweenthose said gear wheels 16 and 1.7 an elongated supporting member 18,which is adapted to support the two trains of gear wheels which areadapted to operate the gear wheels 16 and 17 At one side of the saidelongated member 18 there is a gear wheel 19, which is adapted to meshwith the gear wheel .1 6, and immediately opposite this gear wheel 19there are two gear wheels 2() and 21, the combined diameters of whichare equal to thc diameter' of the gear wheel 19. 'lhe gear wheel 19 alsomeshes with a gear wheel 22 and the gear `wheel 2l) also meshes with agear wheel 23.

Groarwheels 24 and 25 are also jonrnalod to the elongated member .18,but `those gear wheels 24 and .25 are disposed at a slight distance fromthe gear wheels 22 and 23 respectively, and their motion is adapted tohe transmitted to the gear wheels 22 and A23 by means of p-inions 26 and27. 'lhcsc pinions 26 and 27 are journaled in frames .28 and 2Urespectively, and to these frames are pi'voted links 3l) and 31, whicharc pivotcd to cranks 32 and 33 secured to the shaft 5, to which thecrank 4 is also secured. 'lhr'so cranks 32 and 33 are secured at ananglo to cach other, so that it will he seen that as` the crank 4 isoporated the frames 29 and 2) will he operated in dillcrent directions.'lhosc frames 8 and 2l) are adapted to move in guides 34.

'lhe arm Si extends through a slot 555 in the.

casing so that it is adapted to be operated by the thumb or a ringer ofthe user of the typewriter. v

Enmeshing with the gear wheels 24 and 25 are gear wheels 36 and 37.These gear wheels 36 and 37 are secured to a shaft 38 to which is alsosecured therebetween the escapement wheel 39. Pivoted t0 the frame ofthemachine there is an esca-pement lever 40, which has a pallet arm 41, andat the outer terminal thereof there is apallet 42. Opposite this pallet42 there is pivoted to the lever'40 a bell crank lever 43, which has astud 44 at ,the terminal of one of its arms, the stud 44 being adaptedto engage the escapement wheel 39 as a pallet; the other arm 45 o f thebell crank lever is connectedby a link 46 with the arm 470i asecond-bell crank lever pivoted to the lever 40, the other arm 487erthis bell crank lever being connected by a rod 49 which passes throughan opening in the casing 6 to the thumb piece v2, and nearthe outerterminal of the rod 49 thereis the second thumb piece -1 which issmaller in size than the thumb piece 2. The thumb piece 2 is connectedby means vof a'rod 52 with the escapement lever40. At one side voi: thecasirur 6 there is an auxiliary 'casing 53, in which there is a clockspring 54 mounted in the usual-manner, and which is adapted to be woundup in the customary manner. Connected with this clock spring and adaptedto be operated thereby is a gear wheel 5 5, which enmeshes with Aapinion 56,

'said pinion being secured to the shaft 38 which projects through thecasing into the' In the casing are se auxiliarv casing 53. cured in rpads 57 which are so disposed as to press on the face of the characters8 so they will be inked as they pass thereby. A spring 5S is provided tohold the escapemcnt lever 40 upwardly in position,and a spring may alsobe provided to hold the arm 43 of the bell crank lever so disposed thatthe stud 44 will contact with the teeth of the escapement wheel 39.Openings 59 may be provided in the casing so that the identificationmarks ot' the ianges'i4 of the members 11 will bee):- posed to the viewof the operator of the typewriter.

ln using my invention, ink is supplied to the pads 57, and the operatorputs his thumb on the arm 3 of the crank 4 and his fingers on the ringerpieces 1 and 2'secured to the rods 49 and 52. He then by looking at thecharacters' exposed at the opening at the base oi' the casing, Aand alsoby looking at the characters over the openings 59 in the casing isenabled to lee-rn the characters which protrude through the casing, andas these have been inked bytheir passage over the inkers 57, by stamplngVthem on the Writing material heis able to obtain the impressiondesired. When he wishes to use other characters, by means of theoperation of the finger piece 2 he can operate the escapement lever 40which will permit the escapement wheel to revolve under the pressure ofthe spring 53 until the new character is carried and is exposed in theopening at the bottom of the casing t). The escapement lever 40 whenoperated by the linger piece 2, permits onetooth oi the escapemen'twheel 39 to pass the pallet 12, and the teeth in both the lines ofgearing are so adjusted as to permit the belt to travel such a distanceas to project a character in the, said opening in the casing. By meansof theI pinions 26 and 27 the belt 9 may bc moved in either direction,and the characters may, therefore, be carried upwardly or downwardlyover the sprocket wheel 7 as may be desired, the desired train ofgearing being connected by means .of the movement of the arms- 3, whichoperates the mechanism which moves upwardly or downwardly the pinionwhich is adapted to connect the line v ldesires to use a character atsome distance from the opening in the casing 6, he may by pressing thethumb piece l draw the stud 44 away from the escapemcnt wheel 39, permitthe escapement wheel to rotate rapidly and thereby permit the Irearwheels 3G and 37 which are secured to the shaft 3S to oper ate the gearwheels 24 and 25, and in this Way obtain a quick movement ot' thc deesired line of gearing, which will quickly bring to the opening in thecasing 6 the desired character.

[is has been stated, the casing may be so constructed that 'it willpermit ot the letters being' seen at desired places 'therein and anysuitable means may be provided to designate the letter which is inposition for printing. 011e method would be to have the characters onthe sides of the members forming the belt at certain distances from theletters to which they refer, this distance corresponding with thedistance between the letter which is in position for printing and anopening in the casing. are much higher than the belt, so that when drawnover the inkers, the letters will be inked without smearing the inkonthe belt.

Having thus described my invention, what i claim as new `and desire tosecure by Letters Patent is: Y
